It must be kobolds inside your PC case. Do you feed them regularly?

No one's running away from the problem. LOL. We are not AMD, we are users just like you. This is not AMD Support, this is a forum, if you didn't notice. However, we cannot help if you don't provide information. It looks like you still didn't get the post I wrote yesterday. Do you expect us to guess (like I did) or read your mind? We don't even have a clue what kind of computer you have.

Read this thread and provide the information requested. And more, if you can think of anything that might matter and not listed there.
